  • CHANGES in Ph ASSOCIATED with the APPLICATION of AMMONIA and POTASSIUM HYDROXIDE to DIAPAUSING EGGS of TELEOGRYLLUS OOMMODUS (WALK.) (ORTHOPTERA: GRYLLIDAE)
    CHANGES IN pH ASSOCIATED WITH THE APPLICATION OF AMMONIA AND POTASSIUM HYDROXIDE TO DIAPAUSING EGGS OF TELEOGRYLLUS OOMMODUS (WALK.) (ORTHOPTERA: GRYLLIDAE) By T. W. HOGAN* [Manuscript received September 9, 1964] Summary Diapausing eggs of T. commodus were exposed to a:mmonia evolved from solutions of ammonium hydroxide in desiccators for specific periods. It was found that the pH of the egg contents increased with increase in concentration of the ammonium hydroxide and the period of exposure. Toxic symptoms and mortality of eggs were associated with a rise of pH exceeding 0·4 of a unit. This occurred at the higher concentrations, viz. exposure for 3 days to O· 3M or for 2-3 days to 0 ·IM ammonium hydroxide. The most favourable effect on the termination of diapause was with exposure for 3 days to O· 01M ammonium hydroxide, which raised the pH to 7· O. This was also the highest non-toxic concentration. On the basis that the rise in pH might be the causal factor for the termination of diapause, the effect of potassium hydroxide solutions on the pH of the eggs was tested and found to be moderately effective both in this regard and in accelerating the rate of termination of diapause. However, there was some termination of diapause before any significant rise in pH occurred. It appears, therefore, that the action of ammonia and of potassium hydroxide must have a common factor other than raising the pH of the egg contents. 1. INTRODUCTION It has been shown that when diapausing eggs of Teleogryllu8 commodu8 (Walk.) are exposed to ammonia evolved from solutions of ammonium hydroxide for an adequate period, diapause is terminated in a high proportion of the eggs.
